Nora invested $6,300 in an account paying an interest rate of 7\tfrac{3}{4}7 4 3 % compounded continuously. Ella invested $6,300 in an account paying an interest rate of 7\tfrac{1}{4}7 4 1 % compounded monthly. After 11 years, how much more money would Nora have in her account than Ella, to the nearest dollar?

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
